Actually, a lot of straight girls find that nasty. But for the guys,
In fact,
my girlfriend always jokes about having 3 somes with other chicks.... like she wanted me to walk over to her friends house because she was there and it was like 3 and a half miles away, and she said "If you come over here, me you and erin can have a threesome"
Which, was great for me, but I didn't go.
Too far of a walk for some puss, and I'm pretty sure it was a joke.
